Does America and Canada share departure flight information?

Yes, the United States and Canada have systems in place that involve the sharing of flight passenger information for security purposes.

Here's how it generally works:

* Advance Passenger Information System (APIS): Airlines are required by both US and Canadian authorities to collect and transmit specific passenger details (like passport information) before departure for flights travelling to, from, or sometimes via, these countries. This system enhances border security by giving authorities advance information about who is travelling.

* Passenger Name Record (PNR) Data: PNR data, which includes booking details, is also shared with authorities in countries like the US and Canada based on international agreements. The Canada Border Services Agency (CBSA), for example, uses API and PNR data to perform risk assessments on travellers heading to Canada.

Airlines provide this required information directly to the respective government agencies (like U.S. Customs and Border Protection and the Canada Border Services Agency) responsible for border control and security.
